Taking us toward future maniacal laughing zombie apocalypse with brain eating?
Autocannibalism would technically be a way to avoid that scenario.
But it does make me wonder how the people caught ‘mad cow’ disease in the United Kingdom in the 1990s from eating beef? I don’t think they were eating brains. The mad cows were getting infected from being fed feed supplements that contained ground up cattle carcass bits that were left over after butchering.
The other prion disease I find fascinating is the Tasmanian Devil facial tumour disease spread by biting.
Now we have the full sci-fi future horror recipe (or script) with maniacal laughing, face biting, hypersalivating, mutant mad Tasmanian devil cows to watch out for.
